1. Field of the Invention
The present invention relates to a foldable sunshade with a tiltable canopy.
2. Description of the Related Art
A sunshade may provide a comfortable space for outdoor activities. A so-called free-arm sunshade manufactured by Glatz Ltd. includes a main frame, a canopy support frame, and a canopy. Although the canopy support frame of the free-arm sunshade is tiltable (rotatable) in all directions to obtain optimum shade, it is, however, found that the adjustment is troublesome. More specifically, the user has to lower the canopy to a reachable level (otherwise a chair or the like is required to reach the canopy), rotate the canopy, and raise the canopy again. The user must operate the mechanism for adjusting the height of the canopy twice. In addition, the device allowing rotation of the canopy in all directions is complicated and might be actuated by strong wind. Furthermore, the volume of the sunshade is relatively large and thus inconvenient and costly to transport. U.S. Pat. No. 6,152,156 issued to Tung (the Applicant) on Nov. 28, 2000 discloses an improved sunshade that allows easy operation in adjusting the tilting angle of the canopy. The present invention is intended to provide an improved design to allow further folding of the sunshade to reduce the volume for transport.
It is a primary object of the present invention to provide an improved sunshade in which the canopy is tiltable, and adjustment of the tilting angle of the canopy can be easily achieved.
It is another object of the present invention to provide an improved sunshade in which the canopy can be reliably retained in a desired tilting angle.
It is a further object of the present invention to provide an improved sunshade that is foldable. In addition, the canopy support frame together with the canopy can be disengaged from the elbow when not in use.
A sunshade in accordance with the present invention comprises:
a supporting rod having a lower end and an upper end;
an adjusting sleeve slidably mounted around the supporting rod;
a holding sleeve pivotally connected to the upper end of the supporting rod;
an arcuate tube slidably extended through the holding sleeve and including a first end and a second end;
an elbow connected to the first end of the arcuate tube and including an anchor room;
an anchor releasably engaged in the anchor room;
a canopy support frame for supporting a canopy and including a suspension member connected to the elbow, an upper support base having a plurality of ribs attached thereto for supporting a canopy, and a lower support base having a plurality of stretchers attached thereto for supporting the ribs, the lower support base being connected to the anchor;
a reel mounted to the second end of the arcuate tube and including a handle;
a cable having a first end connected to the handle and a second end connected to the anchor, the cable being movable in a retracting direction and a releasing direction;
a connecting rod connected between the second end of the arcuate tube and the adjusting sleeve;
wherein when the handle is operated to release the cable in the releasing direction, the is anchor is disengaged from the anchor room of the elbow while the canopy is folded, and when the handle is operated to retract the cable in the retracting direction, the anchor is moved into the anchor room and thus engages the suspension member with the elbow when the canopy is in a fully opened status;
wherein the adjusting sleeve is slidable along the supporting rod while the arcuate tube is slidable along the holding sleeve to adjust a tilting angle of the canopy relative to the supporting rod;
wherein the arcuate tube includes at least two telescopic tube sections to allow adjustment of an overall length of the arcuate tube; and
wherein the support rod includes at least two telescopic tube sections to allow adjustment of an overall length of the support rod.
The arcuate tube includes a control sleeve to restrain sliding movement of the arcuate tube relative to the holding sleeve. The control sleeve bears against the holding sleeve when the canopy is in an upright position. In an embodiment of the invention, the arcuate tube includes an outer tube section having a first end to which the reel is attached and an inner tube section having a first end telescopically received in a second end of the outer tube section and a second end to which the elbow is attached. The control sleeve is mounted to the second end of the outer tube section and includes a hole aligned with a transverse hole of the outer tube section. An elastic element has a first end securely attached to an inner periphery of the inner tube section and a second end to which a push button is attached. When the arcuate tube is in an extended status, the push button is extended through the transverse hole of the outer tube section and the hole of the control sleeve. When the push button is pushed inward and a longitudinal force is applied to the inner tube section in a retracting direction, the inner tube section is retracted into the outer tube section. When a longitudinal force is applied to the inner tube in a releasing direction, the inner tube section is pulled out of the outer tube section and the push button is extended into the transverse hole of the outer tube section and the hole of the control sleeve under the action of the elastic element when the push button reaches the level of the transverse hole of the outer tube section and the hole of the control sleeve.
The first end of the inner tube section includes an end cap securely attached thereto. The end cap includes a flange in sliding contact with an inner periphery of the outer tube section. A stop is securely mounted around the inner tube section. The stop bears against an end face of the control sleeve for preventing disengagement of the push button when the arcuate tube is in its fully extended status. The stop and the flange assure stable sliding movement of the inner tube section relative to the outer tube section.
The supporting rod includes a lower tube section and an upper tube section which are identical to the arrangements of the inner tube section and the outer tube section of the arcuate tube, thereby allowing adjustment in the overall length of the supporting rod.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring to the drawings and initially to
The supporting rod 12 includes at least two tube sections. In this embodiment, the supporting 12 includes a lower tube section 12a and an upper tube section 12b having a lower end telescopically received in the lower tube section 12a. A control sleeve 13 is mounted to an upper end of the lower tube section 12a for retaining the upper tube section 12b and the lower tube section 12a in place or allowing telescopic movement of the upper tube section 12a relative to the lower tube section 12a, which will be described later. A holding sleeve 18 is pivotally connected to an upper end of the upper tube section 12b at 20. An arcuate tube 24 is provided and includes at least two tube sections. In this embodiment, the arcuate tube 24 includes an outer tube section 24a and an inner tube section 24b having an end telescopically received in the outer tube section 24a. The outer tube section 24a is slidably extended through the holding sleeve 18. A control sleeve 26 is mounted to an end of the outer tube section 24a for retaining the inner tube section 24b and the outer tube section 24a in place or allowing telescopic movement of the inner tube section 24b relative to the outer tube section 24a, which will be described later. An elbow 34 mounted to the other end of the inner tube section 24b and a reel 28 is mounted to an end of the outer tube section 24a. The reel 28 includes a handle 30 for manual operation for folding or unfolding the canopy 3, which will be described later.

Turning to
Referring to
It is appreciated that the control sleeve 13 for the supporting rod 12 includes a structure identical to that of the control sleeve 26 shown in FIG. 11. Thus, when a push button 131 (identical to push button 261) is pushed, the upper tube section 12b can be retracted into the lower tube section 12a to a status shown in FIG. 10. Retraction and unfolding operation of the supporting rod 12 are identical to those of the arcuate tube 24 and thus will not be described in detail to avoid redundancy.
According to the above description, it is appreciated that the tilting angle of the canopy of the sunshade of the present invention can be easily adjusted, and the canopy is reliably retained in the desired tilting position after adjustment. In addition, the whole sunshade can be further collapsed after folding the canopy, which may reduce the cost for transport. Furthermore, the canopy support frame 2 together with the canopy 3 can be disengaged from the elbow 34 when not in use.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
